Designation Status FH 62 C 14 Series Continuous Ambient Particulate Monitor US EPA Automated Equivalent PM 10 Method EQPM-1102 -150 CARB California Approved Sampler (CAS) for PM 10 and PM 2. 5 Model 5012 Multi Angle Absorption Photometer Instrument not designated 4
Series FH 62 C 14 Principle of Operation Thermo Electron FH 62 C 14 Beta 5
Series FH 62 C 14 Principle of Operation (cont. ) 6
Series FH 62 C 14 Principle of Operation (cont. ) C 14 uses Beta Attenuation through known area on filter tape to continuously detect mass of deposited ambient particles Continuous detection of Beta Attenuation is proportional to increased mass C 14 also measures Alpha particle emissions to exclude background interferences from radon gas 7
Series FH 62 C 14 Principle of Operation (cont. ) Clean filter spot introduced by automatic filter change every 24 hours Or sooner if mass on filter exceeds 1500 g since last filter change Or if flow rate is reduced by 5% particle deposition Ambient air is drawn through a size-selective inlet TSP, PM 10, PM 2. 5 8
Series FH 62 C 14 Principle of Operation (cont. ) Ambient particles are drawn down heated sample tube Decrease RH of sample stream Reduce particle bound water Reduces positive artifact measurement of condensation on filter tape Sample tube is curved to avoid abrupt turns and points for premature collection Collection of particles on filter tape and measured continuously 9

Thermo Electron Support Fifteen years experience supporting existing Beta Attenuation units Free phone & email support for setup, maintenance and troubleshooting Component replacement Recalibration services Cleaning services for Measurement chamber 15
Calibration Procedure and Frequency Mass Foil Calibration Performed once a year or after measurement chamber has been cleaned; procedure requires 20 -30 minutes Air Flow Calibration Performed once a year; requires NIST traceable volumetric flow device, Before Air Flow is calibrated, strongly recommended that you calibrate temperature sensors and barometric pressure sensors 16
Verification Stable operation of instrument is verified and monitored by observing Error Status on Main Menu Global Error Sum Status reports verification of following parameters Data and program memory Particulate sampling and measurement system Air flow rate regulation unit External sample tube heater Temperature measurements Each Global parameter is further divided into 8 fields of Detailed Error Status Codes 17
Maintenance Interval Maintenance Procedure 5 -20 days Clean PM-2. 5 impactor or cyclone 1 -3 months Check air flow 3 months 6 -9 months 12 months 2 years Clean PM-10 inlet Check/change filter tape Mass calibration with foil set Air flow calibration Replace pump carbon vanes Clean measurement chamber 18 (by Thermo service)
